No need to say anything is false, this is covered by the statement below.
Also, the driver uses backlight, so it should be true?

The panel uses three power-supplies, so it is not a "panel-simple"
binding. And we cannot have the same compatible twice, so this must be
dropped.

The driver do not use backlight from the DT so disregard the last
comment.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade
